implode are are good for array only mayebe what you need is explode to turn string itno array

[pixeltrace]

how do i do it?

 

sorry im still not very familiar with implode and explode

 

 

thanks!

[teng84]

explode($_GET['poitype']); // array is the output

 

may i know where is this declared          poitype

[sasa]

change

$poitype = implode(",", $_GET['poitype']);

to

if(isset($_GET['poitype']) and count($_GET['poitype']) > 0) $poitype = implode(",", $_GET['poitype']);

[teng84]

change

$poitype = implode(",", $_GET['poitype']);

to

if(isset($_GET['poitype']) and count($_GET['poitype']) > 0) $poitype = implode(",", $_GET['poitype']);

 

cool but what if <0

[pixeltrace]

hi,

 

i replaced it as instructed

$poitype = implode(",", $_GET['poitype']);

to

if(isset($_GET['poitype']) and count($_GET['poitype']) > 0) $poitype = implode(",", $_GET['poitype']);

 

know i am getting errors on this line

 

Notice: Undefined variable: poitype in /var/www/html/myoochi/findit/propertyfindit.php on line 435

the code on this line is this

<? echo "$poitype"; ?>

 

 

whatelse should be done here?

 

thanks!

Unless I'm misreading your original code poitype is an array - that's how you define them in your form.  $_GET['poitype'] shouldn't return anything as you have no variable named $poitype, only array elements $poitype[0], $poitype[1] etc.

[pixeltrace]

i see.

 

thanks!

[sasa]

change

if(isset($_GET['poitype']) and count($_GET['poitype']) > 0) $poitype = implode(",", $_GET['poitype']);

to

if(isset($_GET['poitype']) and count($_GET['poitype']) > 0) $poitype = implode(",", $_GET['poitype']); else $poitype = 'Nothing selected! ';

thanks!

 

everything is ok now!
